curious visitors

where do you go when you leave? out into the woods, into the dry desolate desert. where do your wings take you? when they can take you so far. to me it seems like you appear and then just as quickly disappear. your beautiful appearance is striking when you come into the yard.  sometimes you stay longer than others, nesting in trees and bushes. sometimes i know what you are at your beginning. but where do you go when you are at your end? your bodies aren't found. you seem to fly to the heavens and never appear again. no feathers remain. your soft sounds are heard no more. the leaves take you in their place, the sands dust your memory away. but all i know is that you were here once and that one song or brilliant color you showed me will be in my heart forever.
